Expression of phosphorylated Stat3 (p Stat3), c fos and c jun proteins was detected by immunohistochemical technique in 55 hepatocellular carcinomas (HCC) and their surrounding liver tissues. The results showed that the positive rates and signal intensity of p Stat3, c fos and c jun protein in HCCs were significantly higher than those in pericarcinomatous tissues. The expressive intensity of c fos and c jun proteins was positively related to p Stat3 expression in HCCs, whereas the posit...
